Parabolic Hyperboloid Roof

The growing popularity of this roof is rooted in a seemingly contradictory characteristic of its shape.

Parabolic hyperboloid roof.

The exhibition hall is 135m long and enclosed by two hyperbolic paraboloid roofs rising to a central ridge 29m high. It is also a doubly ruled surface that is every point on its surface lies on two straight lines across the surface. The entire roof structure rests on only two supports giving it an appearance somewhat resembling a bird in flight. The warszawa ochota railway station has a hyperbolic paraboloid saddle roof warsaw poland 1962.

The hyperbolic paraboloid is a doubly ruled surface so it may be used to construct a saddle roof from straight beams. Roof construction in the united st a t e s it seemed that domes would be the o r der of the day for decora t i v e ap plication and barrels for utilitari a n b u i l d i n g s. Mcgraw hill dictionary of architecture and construction. This up and coming thin shell roof type is the hyperbolic paraboloid.

However a the hyperbolic paraboloid as a thin shell roof type is making inroads in these markets. A hyperbolic paraboloid not to be confused with a hyperboloid is a doubly ruled surface shaped like a saddle in a suitable coordinate system a hyperbolic paraboloid can be represented by the equation. His work with thin shell concrete roof structures broke barriers between architecture and engineering that opened the way for other architects such as santiago calatrava. He is celebrated for his feats of architectural engineering that transform concrete into visual poetry with his structural design based on hyperbolic paraboloid geometric form.

A hyperbolic paraboloid sometimes referred to as h p is a doubly curved surface that resembles the shape of a saddle that is it has a convex form along one axis and a concave form on along the other. In this position the hyperbolic paraboloid opens downward along the x axis and upward along the y axis that is the parabola in the plane x 0 opens upward and the parabola in. The roof structure consists of cranked trusses formed from straight tubular members each truss set at a different angle to create the compound curve.
